for varying the amount of the commodity delivered from the machine. Fig. 10 is a side elevation of the machine taken from the right hand side of Fig. 1. Fig. 11 is a detail sectional view on line 1111, Fig. 8.

Referring more particularly to the drawings and in the present exemplification of the invention the numeral 10 designates four uprights or posts upon which the mechanism is supported and these uprights are mounted upon a suitable base 11. The uprights are provided throughout a greater portion of their length, preferably the upper portions, with screw threads 12 for a purpose to be hereinafter set forth. Supported by the uprights, preferably by their upper ends, are

spaced members 13, 14, preferably in the form of disks or plates (see particularly Figs. 5 and 7) between which a rotating disk 15 is disposed and these members 13, 14, serve as a housing for the disk. The members 13, 14, may be of any desired configuration but are preferably circular as shown,

and passing through the center of the plates is an upright shaft 16 to which the hub 17 of the disk 15 is connected, preferably by means of a fastening device 18 and the shaft 16 is provided with a groove or Way 19 for a purpose to be set forth. Secured to the shaft 16 is a worm wheel 20 which is located preferably above the member 14 and a worm gear 21 (see also Fig. 1) meshes with the worm gear 20. This worm gear 21 is connected to a shaft 22 which latter is journaled in suitable bearings 23 supported by any fixed portion of the mechanism preferably by the member 14 so that the shaft 22 will be disposed at right angles to the shaft 16. A motor 24 having a shaft 25, is supported by a suitable bracket 26 so that the shaft will be disposed in proximity to the shaft 22 and preferably at right angles thereto. A friction driving gear 27 is secured to the shaft 25 to rotate therewith and cooperates with a friction disk 28 secured to the shaft 22. In order to hold the disk 28 against the driving gear 2?, an elastic member 29 in the form of a coil spring is provided which surrounds the shaft 22 with one end of the spring engaging a collar or shoulder 30 on the shaft 22 and the other end bearing against one of the bearings 23 of the shaft 22 so that when the shaft 25 is rotated, the motion thereof will be transmitted through the medium of the friction gearing 27, 28, to the shaft 22 which in turn will rotate the worm gear 21 and the latter will r tate the worm gear 20 as well as the shaft 16. Inasmuch as the disk 15 is secured to the shaft 16 it will be manifest that when the latter is rotated the disk will be correspondingly rotated. This disk 15 is provided with an aperture or opening 32 therethrough, as shown more clearly in Fig. 4,

and one edge of the opening is beveled or inclined as at 33 for a purpose to be set forth.

In order to vary the speed of rotation of 1 the shaft 22 and consequently the disk 15,. the casing of the motor 24 is provided with f a bearing 34 into which the extremity 35 of An adjusting SCI'GWf 36 is threaded into this bearing 34 and is provided with a contact portion 37 adapted to engage the extremity 35 of the shaft 25 the shaft 25 projects.

so that when the screw 36 is adjusted in one direction, the shaft 25 will be moved longitudinally to move the friction gear 27 toward the axis of the disk 28 and against the tension of an elastic member 38, which latter surrounds a portion of the shaft 35,

with one extremity having engagement with a bearing 38 in which the shaft 25 is jour naled, and the other extremity of the elastic member has engagement with the sleeve on collar 40 which is adjustably mounted on the shaft 25. hen the screw 36 is ad justed in the opposite direction the elastic member 38 will tend to move the friction gear 27 toward the periphery of the disk 28. In order to permit the shaft 22 to be moved longitudinally in its bearings 23 and without disconnecting the worm gear 21 with respect to the gear 20, the worm gear 21 is connected to the shaft 22 by means of a feather connection comprising grooves in.

the shaft and in the worm gear and a key 41 (see Fig. 2) which enters the grooves. The member 13 is provided with an aperture or opening theret'hrough with which the opening 32 in the disk 15 is adapted to register, and a hopper 42 having a reduced out-, let portion 43 is supported in any suitable manner so that the outlet will register with the opening in the member 13.

A tubular member 44 (see particularly tubular member 46 the tubular member 44' telescopes. This member 45 is supported by means of the uprights 10 and is provided with hangers 47 within which are arranged gears 48, one for each of the uprights 10.

These gears 48 are preferably in the form of nut-s or collars having internal screw threads which cooperate with the threaded portions 12 on the respective uprights 10. The peripheries of these gears 48 are provided preferably with worm threads with which worm gears 49 mesh. One of these gears 48 is provided for each of the uprights 10 and one of the gears 49 is provided for each of the gears 48. Shafts 50, which are journaled in suitable bearings preferably the hangers a-re provided and these shafts connect the gears 49 in pairs. A shaft 51 (see Fig. 7) is journaled in suitable bearings carried by the member 45 and is arranged transversely of the shafts 50. Carried by this shaft 51 are worm gears 52 which mesh with worm gears 53 on the respective shafts 50. An operating handle 54 (see particularly Figs. 1 and 7) is connected with one end of the shaft 51 for rotating the latter. A pair of members 55, 56, similar to the members 13, 14, are supported by the uprights 10 below the member 45 and one of these members, preferably the member 55, is provided with hangers 57 in which are journaled gears 58 similar to the gears 48. These gears 58 are provided with internal threads (see also Fig. 9) which cooperate with the threads 12 on the uprights 10 and are also provided with peripheral worm threads. A worm gear 59 meshes with the worm threads on the periphery of each of the gears 58 and shafts 60 are provided which connect the gears 59 in pairs similar to the gears 49. Each of the shafts 60 is provided with a worm gear 61, and worm gears 62 on a transverse shaft ('33 mesh with the respective worm gears 61. This shaft 63 is journaled in suitable bearings carried by the member 55.

The shaft 51 is arranged above the shaft 63, and'motion is imparted to the latter shaft from the shaft 51 through the medium of a gear 64 (see Figs. 1 and 7) on the shaft 51, which meshes with a gear 65 (see also Fig. 9) on an upright shaft 66 and this shaft 66 has a sliding connection with a gear 67 which latter meshes with a gear 68 carried by the shaft 63. It will thus be manifest that when the crank 54 is rotated to rotate the shaft 51, the shaft 63 will also be rotated and as these two shafts 51, 63, are rotated the respective gears 48, 58, will be rotated upon the uprights 10 and will be moved up and down said uprights, according to the direction of rotation of the handle to cause the members 45 and 55, 56, to travel. toward or away from the members 13, 14. The members 55, 56, are spaced from each other similar to the members 13, 14, and as littlall shown in Fig. 7 and the shaft 16 passes through these members 55, 56. A disk 69 similar to the disk 15 is provided with an aperture 7 (see Fig. 1) similar to the aperture 32 in the disk 15 and this aperture 70 is provided with a beveled or inclined edge 71 similar to the inclined edge 33. The disk 69 is connected with the shaft 16 for rotation therewith and for adjustment longitudinally with respect to the shaft, such as by means of a key which travels in the groove 19 in the shaft 16, so that when the members 55, 56, are adjusted or moved upon the uprights in the manner above set forth, the disk 69 will be correspondingly moved so as to move the disk toward or away from the disk to vary the distance between the disks.

The members 55, 56, are provided with openings therethrough which register and these registering openings are adapted to register with the openings in the members 3, 14:. A tubular member 72 is supported by the member 56 and surrounding the opening therethrough and the tubular member 72 is of such a size and configuration that it will receive the tubular member 46 as shown more clearly in Fig. 6 so that when the members 55, 56, and as, are moved toward the top of the uprights 10, the tubular members 72, 46, eta, will telescope with each other as shown in Fig. 6, and, together with the tubular member 43, will form a chambered outlet for he hopper. The gears 58, 59 and 48, 4.9, are so proportioned with respect to each other that the gears 58 will rotate approximately twice as fast as the gears 4L8 so that when the parts are adjusted from the position shown in Fig. 10 by the operation of the handle 54:, the members 55, 56, will travel twice as fast as the member t5 so that by the time the member L5 reaches the member 13, the members 55, 56, will move into the position shown in Fig. 6. A discharge spout 7 3 is supported by the member 55 to receive tne material discharged through the members 55, 56, and this spout 73 may be of any desired configuration but preferably of a configuration to adapt it to be inserted into a bag or other receptacle. The hopper 42 is preferably arranged to one side of the shaft 16 and on the side opposite to that on which the motor 24 is attached.

In use the disk 69 is first ad usted with respect to the disk .15 so that the space within the tubular telescoping members 44, 46, 72, will hold the exact amount of the commodity to be placed within the package. Having once been thus adjusted, the motor is then started. This will rotate the shaft 16 as well as the disks 15, 69. As soon as the disk 69 reach s a position that its opening 70 will register with the telescoping tubular members, the commodity in the space between the disks 15, 69, within the tubular members, will be released so as to be discharged through the outlet 73 and into the receptacle. By the time this quantity of the material has been thus discharged a solid portion of the disk 69 will extend across the tubular members to form a closure therefor and thereby shut ofi the discharge of the material. At the same time the disk 15 will assume a position that the opening 32 therein will be adjacent the hopper to permit another supply of the commodity or material to be deposited upon the disk 69. A further rotation of the disk 15 will shut oh" the supply of the material until that amount which is contained between the disks and within the telescoping tubular members has been discharged. The disks rotate in the direction indicated by the arrow in Fig. 4:, that is, in a direction so as to cause the beveled edges 33 and 71 to be presented to the material so as to out of the supply and thereby avoid damage to the material.

When it is desired to vary the speed of rotation of the disks all that is necessary is to adjust the screw 36 to shift the motor shaft 25 longitudinally and thereby vary the position of the friction driving gear 27 with respect to the friction disk 28 by moving the driving gear 27 toward or away from the periphery of the disk 28.
